What’s Ed Miliband playing at?

There’s that prism I mentioned: Ed Miliband writes an article for the Observer, which ostensibly backs Gordon Brown in the first paragraph, and it’s written up as the first, tentative step on his own leadership campaign.  Thing is, that’s probably also true.  The clue is in how far he steps off his ministerial beat*, to deliver an overall prospectus for the Labour Party:

“Let’s start, as our manifesto will, with what the country needs in the coming five years. It can’t be about business as usual. We need to rebuild our economy in a different way from the past, with more jobs in real engineering not just financial engineering. This economy of the future can only be created if we understand the role of government, complementing the private sector, in making it happen, nurturing industries from digital to low carbon. The last thing Britain needs is a government that thinks its only role is to get out of the way.
